Been pulled over twice in the 5,000km I've driven my Adub :)
Completely stock exterior, lowered (TRD springs), stock teardrops, stock exhaust, full licence, etc. Windows are tinted though.
Basically put it down to bad luck - both times I had an unmarked car behind me without realising, once I went around a corner "a bit too quick" and chirped the tyres, the other time I accelerated through a roundabout at a t intersection without slowing down much. Both times a warning was given, to drive a bit more carefully :) If I was in my Mazda 2 I may/may not have been pulled over - I don't think I was being targeted - but if I was in the Mazda I wouldn't have been going round corners that quick anyway ;)
I think the MR2 is unique enough that It doesn't have the cop-magnet effect that a silvia, supra, skyline, etc has (as long as it's not bright pink with a cannon exhaust and 18 inch chrome rims). It seems to cost more to get big power out of an mr2 as well, and so has less of a hoon reputation.
MRTurboIt's more fun driving a 'slow' car 'fast' :D
